Abstract:

In this study, a field experiment was conducted to compare photosynthetic physiological characteristics and the chlorophyll fluorescence parameters in leaves among five Carya illinoensis varieties, including Farley, Colby, Shoshoni, Cheyenne and Mandan. The results showed that there were significant (P<0.05) or highly significant (P<0.01) differences in minimal fluorescence (Fo), maximum fluorescence (Fm), PSⅡ potential activity (Fv/Fo) and non-photochemical quenching (NPQ) among the five varieties. The Fo and Fm of Shoshoni were higher than that of the other cultivars. The PSⅡ primary energy conversion efficiency (Fv/Fm) and PSⅡ potential activity (Fv/Fo) of Mandan were higher than those of the others, while the value of NPQ was lower. The light compensation point (LCP) of Mandan was significantly lower than that of the other varieties, indicating that it had a strong ability of using low light. Mandan and Shoshoni had higher maximum net photosynthetic rate (Amax) and relative chlorophyll content (SPAD). Results of the correlation analysis showed that there were significant positive correlations between Fv and Fv/Fm, Amax and SPAD. A significantly negative correlation was found between NPQ and Fv/Fo.

Key words: Carya illinoensis, photosynthetic physiological characteristics, chlorophyll fluorescence, relative chlorophyll content, correlation
